The "Hello World!" of physical computing. This is the first project / circuit to get you started with Arduino and the Sparkfun Inventor's Kit.
Upload this example to your board. Play around with the timing delays. What is the fastest blink that you can still see?
Can you create a simple Morse code message with the blink patterns?
How about a heart beat? Re-create a heart-beat pattern using a sequence of ON and OFF patterns. How realistic can you make it?
